The Best Filter Media From The Worlds Finest Filter Manufacturer

Reviewed in the United States on December 7, 2012

Verified Purchase

I've been keeping fish for close to 40 years and have been a die hard eheim fan for nearly as long. Gunter Eheim was an engineer with vision and created the first line of filters to incorporate biological, mechanical and chemical filtration in single systems.

The Pro series remain the finest filters money can buy. However the cost is steep although worth any penny. Regardless of the canister filter you own 90% of it's effectivness can be directly related to the quality of media you use. Without question eHeim's substrate pro will colonize nitrifying bacteria faster, quicker and more of it than most any media I've tried.

The material, Sintered glass has a remarkable amount of places for healthy bacteria to colonize, the shpere shape increases this amount over cermaic rins dramatically and the results are easy to see and see quickly. Lower nd fewer amonia spikes, stablized water parameters - and best of all healtheir happier fish.

Unlike most media sintered glass really doesn't break down like finished or or unfinished ceramic - nor does it loose its effecency like plastic BioBalls (great for wet dry systems - not for canister filters) Because you'll probably never have to replace these - the media pays for itself many times over as you'll get years of use out it.

A terrific media that really delivers exceptional results - your fish will thank you for it.

Large volume of media, very porous.

Reviewed in the United States on May 3, 2021

Verified Purchase

Stuff seems pretty nice. Could probably fill six to eight fluval 207 canister filter media baskets. And the 207 only has three. Bought way more than I needed with this but it's an excuse to get more tanks I guess. Could fill a nice large column in a sump with it I'm sure or several bottle style air/sponge filter style DIY filters. Very porous stuff. Pretty dusty. I'd wash it if you can.

The media could not be loaded.

I use this in my Ecco pro 300 in a 25 gallon guppy tank with an inline UV lights. I have had the same guppy strain in this tank for over 8 years with no problems. Not one sick fish. The water is always crystal clear. I also do a 20% water change each week. I also use Pothos plants to maintain water clarity. No carbon, no ammo chips, no chemicals, nothing but water. I have been using Eheim filters, and other products since 1982.

I bought this to replace the filter media in two of the three trays in my Fluval canister filters. This stuff is awesome. Definitely better than Matrix, and Fluval's stuff.

Good product but not the best

Reviewed in the United States on October 5, 2021

Verified Purchase

When you read about this article, you think that this is the best product, but it isn't.

This is better than ceramic rings, with a density about 450 m²/l, but if you compare this product against biohome (506 m²/l), Matrix (700 m²/l), or JBL Micromec (1500 m²/l), this is not the best competitor.

Don't think that this is bad, it works grate against ammonia and Nitrites, buy it's density doesn't work really well with Nitrates.

If you also want to control Nitrates, I recommend you JBL Micromec or Matrix. They do control Ammonia, Nitrites and Nitrates.

Best of the best

Reviewed in the United States on February 2, 2016

Verified Purchase

Possibly the best more versatile bio media. Has a nice size to it, size ranges from 5-7ish mm. Seems to be a very porous surface. Compared to other medias, like ceramic rings or Seachem Matrix (I've bought large quantities of matrix, and the material seems to vary greatly, even including what looks like rocks and slate.
Will not slip through Rena XP trays.
Doesn't cut up media bags.
Has a relatively long life, the balls breakdown over several years. (Faster if you rinse more often) (you'll notice a small silica sand like sand in your tanks floor.

Very porous

Reviewed in the United States on January 24, 2020

Verified Purchase

I checked how fast it wicks water, and it sucks water up meaning it's s as porous as I was hoping. The balls are pretty small, so for most filters, it's best to keep it in a mesh bag. Be sure to rinse it before use.

Great biological filter media works well. Use it in all 4 of my aquariums. It will take 5 to 6 weeks to cycle your aquarium.

Great Bio Media!

Reviewed in Canada on February 7, 2019

Simply the best bio media out there. One thing to note is that it’s smaller pebbles than usually. Not sure if that is a recent change or I just haven’t bought any in a while.
